Setup Sentry Logging

Configure Sentry's structured logging feature.

Invoke This Skill When

• User asks to "setup Sentry logging" or "capture logs in Sentry"
• User wants to integrate logging libraries (Pino, Winston, Loguru) with Sentry
• User asks about Sentry.logger or sentry_sdk.logger

Quick Reference

JavaScript Setup

1. Verify SDK version

grep -E '"@sentry/(nextjs|react|node|browser)"' package.json

2. Enable in Sentry.init()

Sentry.init({
  dsn: "YOUR_DSN",
  enableLogs: true,
});

3. Console capture (optional)

integrations: [
  Sentry.consoleLoggingIntegration({ levels: ["warn", "error"] }),
],

4. Use structured logging

Sentry.logger.info("User logged in", { userId: "123" });
Sentry.logger.error("Payment failed", { orderId: "456", amount: 99.99 });

// Template literals (creates searchable attributes)
Sentry.logger.info(Sentry.logger.fmt`User ${userId} purchased ${productName}`);

Third-party integrations

Python Setup

1. Verify SDK version

pip show sentry-sdk | grep Version

2. Enable in init()

sentry_sdk.init(
    dsn="YOUR_DSN",
    enable_logs=True,
)

3. Stdlib logging capture (optional)

from sentry_sdk.integrations.logging import LoggingIntegration
integrations=[LoggingIntegration(sentry_logs_level=logging.WARNING)]

4. Use structured logging

from sentry_sdk import logger as sentry_logger

sentry_logger.info("User logged in: {user_id}", user_id="123")
sentry_logger.error("Payment failed", order_id="456", amount=99.99)

Loguru integration

from sentry_sdk.integrations.loguru import LoguruIntegration
integrations=[LoguruIntegration(sentry_logs_level=LoggingLevels.WARNING.value)]

Ruby Setup

1. Verify SDK version

bundle show sentry-ruby

2. Enable in init

Sentry.init do |config|
  config.dsn = "YOUR_DSN"
  config.enable_logs = true
  config.enabled_patches = [:logger]  # Optional: capture stdlib Logger
end

3. Use structured logging

Sentry.logger.info("User logged in")
Sentry.logger.error("Payment failed. Order: %{order_id}", order_id: "456")

Log Filtering

JavaScript

beforeSendLog: (log) => log.level === "info" ? null : log,

Python

def before_send_log(log, hint):
    return None if log["severity_text"] == "info" else log
